Well i started with GOO on a mdf diy screen,then after much debate [same as you] i ordered draper m1300 material £80 for a 7ft diag screen. This did not work out, material was faulty.
I had a sample of drh stuff and was not impressed , anyway as i was stuck i went down to Dunelm [drapery store] and found a new roll of blackout material,i thought quality was on a par [being kind here guys..before you start

] with drh and went for it, at a cost of £17.97
This stuff is brilliant for my set up works great with my infocus 7200, so good in fact i will not be upgrading to a beemax,
I used the non cloth side look at my "post screen disaster..." on this forum pics posted.
Please note i am VERY fussy about image quality and could not believe the image from this stuff..honestly ******** to the "you must have a £700+ screen for a £2500 projector crowd..GOBSMACKED!

If you have or intend to get a similar pj this is the way to go..and please note i would spend the cash if i felt the need.
